APPARATUS FOR BUILDING RETAINING-WALLS.

To all whom it may concern:

Be it known that I, FRANK M. TALBOT, of Glen Ridge, in the county ofEssex and State of New Jersey, have invented certain new and usefulImprovements in Apparatus for Building Retaining-VValls; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention contemplates improved means for building retaining wallshaving special reference to such as may be erected beside a railroadtrack where it is desirable that the travel be not interrupted onaccount of the building work.

I provide a form and supporting scaffolding arranged entirely at oneside of the track, the stays or braces being secured to the scaffoldingand preferably anchored to the ground on which the wall is to be builtand later constituting a metal reinforce for the concrete wall.

In the accompanying drawing, Figure 1 is a side elevation showing a wallform constructed in accordance with my invention, the first stage ofbuilding the wall having been completed. Fig. 2 is a front elevation.

Referring to the drawing 1 designates a frame carrying a verticallymovable form 2 shown suspended by falls 3 wound upon drums or sheaves 4.The form is designed to bear against the frame through the medium oflugs 5 and wedges 5 contacting with the vertical pieces 6 thereof, andthe frame is erected just beyond, or outside of, the plane to beoccupied by the outer face of the wall. lVhen the frame is set up abrace rod 7 is secured to it near its lower end by a turnbuckle 8 andextended diagonally through the space which the wall will occupy andanchored to the ground. The structure is now securely supported and bymeans of the turnbuckle 8 the frame may be trued or adjusted to bring itand the form into the desired position. When this has been accomplishedthe form is lowered, the wedges 5 driven in and the first filling issupplied. In doing this there is sufiicient clearance to enable thematerial, as concrete, to be brought directly over the place it isintended to occupy, none of the parts constituting the form or itssupport in any way interfering with the transportation and dumping ofthe material. When the height of the material reaches the top of form 2the latter is ele- Spccification of Letters Patent.

vated for the next step and so on to the full height of the wall. Afterthe first l'ill has been completed and the form raised, an anchor 9 isplaced in the concrete. This anchor holds a nut- 10 on the end of a bolt12 passed through and secured to the frame. This anchor tends to resistthe pull of the brace rod and maintain the position of the frame andform. When the wall reaches the turnbuckle the latter may be removed,leaving the rod in the concrete where it acts as a metal reinforce.Another brace rod 13 may then be utilized, secured to the ground or tothe top of the portion of the wall just erected and connected with theframe by a turnbuckle as at 1%, and this rod in turn, when the wallreaches it, is disconnected and allowed to form part of the wall. l/Vhenthe wall is completed the bolt 12 is removed and the structure is thenentirely free of the wall.

Practice has demonstrated that by my method the building of retainingwalls is greatly simplified. There is no part of the structure extendingover the railroad track,

should the wall'be built beside one. All of the supporting elements areat the inner side of the frame, as well as the form. The brace rods mayeasily be set up and by allowing them to form part of the finished wallthe work is simplified and the concrete is given a metal reinforce,while the anchor insures the frame being held as against the pull of thebrace rods.

I claim as my invention 1. Means for building a retaining wall beside away or track comprising a frame between the track and the line of thewall, and means for supporting and bracing said frame wholly on the sideaway from said track to leave the latter unobstructed, said meanscomprising a brace rod removably secured to said frame and anchored tothe foundation of the portion of the wall to be constructed, andextending through the space to be filled.

2. Means for building a retaining wall beside a way or track, comprisinga frame between the track and the line of the wall, a vertically movableform carried by said frame, means for supporting and bracing said framewholly on the side away from said track to leave the latterunobstructed, said means comprising an inclined brace rod removablysecured to said frame and anchored to the foundation of the portion ofthe wall about to be constructed and extending through the space to befilled, means for raising and lowering said form, and means for securingsaid frame to the composition filling.

3. In an apparatus for building a retaining wall, the combination withthe vertical frame, the inclined brace rod secured to the ground overwhich the wall is to be constructed and extending up through the spaceto be filled, and the turnbuckle for removably securing said brace rodto said frame and adjusting the disposition of said frame, of a formcarried by said frame, and means for raising and lowering said form.

4. In an apparatus for building a retaining wall, the combination withthe vertical frame the inclined removable brace rods anchored to thefoundation of the portion of the wall to be constructed, and extendingup through the space to be filled, and means for removably securing saidbrace rods to said frame, of a Vertically movable form carried by saidframe, lugs between said frame and said form, and liners or wedgesbetween said lugs and said frame.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
